Follistatin 344

Follistatin 344 – Research-Grade Recombinant Protein

Follistatin 344 is a recombinant protein corresponding to the 344–amino acid precursor isoform of follistatin, a naturally occurring activin-binding protein. This construct is structurally distinct from short synthetic peptides and represents a single-chain, multi-domain protein system produced using controlled recombinant expression techniques.

In laboratory research settings, Follistatin 344 is utilized as a reference material for studying protein–ligand interactions, activin and myostatin binding dynamics, and structure–function relationships within the TGF-β signaling superfamily. Its defined amino acid sequence allows researchers to investigate functional domains and binding behavior without reliance on heterogeneous biological extracts.

Unlike small peptides or peptide fragments, Follistatin 344 exhibits higher-order protein folding and may undergo post-translational modification depending on the expression system. As such, it serves as a useful model for controlled biochemical and molecular biology research conducted in vitro. This material is intended strictly for laboratory research use only and is not designed for human or veterinary application.
